Speciication of Letters Patent. patented Maty' 1921.
Application filed December 11, 1919. Serial No. 344,035.
Vunauthorized person attempt to open thev seal.
To this end the invention consists of the hereinafter described features of construction. ln the accompanying drawings the invention is embodied in a concrete and preferred form in which- Figure 1 is a view of a portion of a freight car with the shackle seal of my invention in position.
Fig. 2 is a plan view of an unbent blank showing one form of shackle seal embodying the invention. Y
Fig. 3 is an edge view of Fig. 2.
Fig. 4 is a viewfpartly in section looking in the direction of arrow 4 of Fig. 1.
Fig. 5 is a sectional view on the line 5 5 of Fig. 4.
Fig. Gis a view similar to Fig. 5 showing how the metal is-fractured when it is attemped to open the seal.
Fig. 7 is a plan view of a blank showing one modified form of the invention.
Fig. 8 is a plan view of a blank showing another modified form of the invention.
Fig. 9 is a plan view of a blank showing a third modified form of the invention.
Fig. 10 is a view of the blank of Fig. 9 bent up and sealed.
1 is a blank of sheet metal in strip form having near one end notches 2 in one of its longitudinal side edges. Near its other end and in the opposite longitudinal side edge of the blank are notches 4. Between notches 2 is a tongue portion 3, and between notches 4 is a recessed tongue portion 5. 6 is a telltale lug forming a continuation of tongue 5,
and separated therefrom by a weakened zone 7 In practice, the blank 1 is passed through hasp or other members 8 of the device with which the invention is to be used,` after which said blank is formed into a loop, as seen bestV in Fig. 4, and the complementary notches 2 and 4 are interlocked` by crossing the parts as shown in Fig. 4. This interlocking prevents longitudinal displacement of thel two ends of the blank. The tell-tale lug 6 is now folded along the weakened line 7 over the complementary tongues `and notches. An unauthorized person, desiring to open the seal, must necessarily unbend lug 6 and this causes thematerial t0 fracture along the line 7 thereby leaving evidence that the seal has been tampered with.
lln the form of thev invention shown in Fig. 2, the sc al number,^9, is carried'by the strip 1, but 1n Fig. 7 a tail 10 carried by lug 6V is provided with the seal number. In.
cause if the blank is thus cut the interlocking parts would become displaced. Strucky up portions 12 are also provided in the ends of the strip. Should the blank be severed at a point outside the seal and an attempt be made to slide the severed end into the seal,
said portions 12 will prevent this being done.
A characteristic feature of the invention resides in the fact that the person using the seal receives it in blank form, and the last act of sealing is the folding over of the telltale lug. There is no previously bent upV socalled caslng socommon in other seals ofy this general character.
l claim:
1. A shackle seal blank comprising: a sheet metal strip having complementary notches formed at opposite ends-'and in the opposite longitudinal edges of the strip, said blank being bent backupon itself to form a loop and the free ends thereof being crossed and the notches interlocked to prevent longitudinal displacement of the two ends ,of
the strip, and a lugprojecting from oneof the side edges only of the strip to be folded over the interlocked parts.
2. A' shackleseal blank comprising: a-
sheet metal strip having complementary notches formed at opposite ends and in the opposite longitudinal edges of the strip, said blank being bent back upon itself to form a loop and the free ends thereof being crossed and the notches interlocked to prevent longitudinal displacement of the two ends of the strip, a tell-tale lug projecting from one of the side edges only of the strip to be folded over the interlocked parts, said lug having a weakened Zone at the line of folding to cause fracture of the material when unbent.
3, A shackle seal blank comprising: a sheet metal strip having complementary notches formed at opposite ends and in the opposite longitudinal edges of the strip, said blank being bent back upon itself to form a loop and the free ends thereof being crossed and the notches interlocked to prevent longitudinal displacement of the two ends of the strip, a tell-tale lug projecting from one of the side edges only of the strip to be folded over the interlocked parts, said lug having a weakened zone at the line of 'folding to cause fracture of the material when unbent, and said lug having an opening to render the interlocked notches visible.
4. A shackle seal blank comprising: a sheet metal strip having complementary notches formed at o posite ends and in the opposite longitudinal3 edges of the strip, said blank being bent back upon itself to form a loop and the free ends thereof being crossed and the notches interlocked to prevent longitudinal displacement of the two ends of the strip, a tell-tale lug projecting from one of the side edges only of the strip to be folded over the interlocked parts, said lug having a weakened zone at the line of folding to cause fracture of the material when unbent and said lug having an opening to render the inter-locked notches visible, and struck-up portions adjacent the ends of the strip.
